The visual actual conditions of above condition increase or change.
Realize that by an embodiment train Unmanned Systems is specially Train Control:
Judge the position of train by described status information, when the train process enters the station the position, described train personal vehicle system control train is parked in specifies passenger's boarding position, 3 seconds rank rear car door openings, front 3 seconds closing of the doors at described train personal vehicle system control launch train, described car door opening and described closing of the door are reminded by the tinkle of bells, if sensor breaks down when detecting car door opening or closing of the door, then by automatic train protection system failure message is sent to man-machine interactive system, driver checks.Described train personal vehicle system control train rolls the station away from and train is travelled with setting speed.Described entering the station is setpoint distance between position and the described appointment passenger boarding position, approach line angle, platform length or other conditions difference because of each station in the reality, enter the station position and specify passenger's boarding position to need to set as the case may be, distance between the two is also just different.Described train is parked in specifies passenger boarding position and described train to roll away to be setting-up time between the station, and the passenger flow volume at station has uncertainty, so the parking period of train need to be set according to actual conditions.Described entering the station has at least one position reference point between position and the described appointment passenger boarding position, and being used for described train automatic Pilot is the control train speed, to guarantee passenger's by bus safety and ride comfort.
When the train process enters the station the position, described train personal vehicle system is inquired about the position and go out distance between the station location of entering the station at current station, and detect the train present speed, making described train present speed by the setting acceleration/accel is zero in described appointment passenger boarding position.For guaranteeing traffic safety and passenger safety, acceleration/accel generally is set as the pattern of at the uniform velocity successively decreasing, and also can be set up on their own by the train personal vehicle system according to actual conditions.
Distance between the actual stop position of described appointment passenger boarding position and train is during greater than setpoint distance, described train personal vehicle system control train reenters described appointment passenger boarding position, until the distance between the stop position of described appointment passenger boarding position and train is less than setpoint distance.When reentering out station location and surpass No. 3 trains and still be not parked in the setpoint distance, stop to passenger's boarding position by man-machine interactive system driver manual drive train.
(2) below described status information satisfies during arbitrary condition, described train personal vehicle system withdraws from the automatic control to train immediately, and by described man-machine interactive system driver:
A, interrupt described train personal vehicle system to the automatic control of train by described man-machine interactive system;
B, described train personal vehicle system or described sensor break down;
C, Train door are not normally closed;
D, the current setting of train do not allow described train personal vehicle system to continue train is controlled automatically;
E, train system are reported the fault that train can't continue to travel to automatic train protection system;
F, platform stopping accuracy can't satisfy the requirement that the continuation of train personal vehicle system is controlled automatically to train;
G, the same day, the train operation task all finished.
The visual actual conditions of above condition increase or change.Below describe by two kinds of situations:
A. the train section of returning withdraws from the driverless operation pattern: come to a complete stop at the train section of returning conversion rail, ATP control man-machine interactive system prompting driver confirms to withdraw from driverless operation and returns section, to be confirmed after, by the chaufeur pilot steering train section of returning.
B. fault withdraws from the driverless operation pattern: when barrier need to withdraw from the driverless operation pattern for some reason, ATP control man-machine interactive system shows the information of " confirming that driverless operation withdraws from ", and show the fault cause that causes the driverless operation pattern to withdraw from, wait for that simultaneously the driver presses acknowledge button.After the driver pressed acknowledge button, system withdrawed from the driverless operation pattern, transferred someone to and drove.According to fault type, need to implement emergency braking in the part situation, need to rebulid the movable block runlevel after withdrawing from the driverless operation pattern in the part situation.
When withdrawing from the driverless operation pattern because of any reason, the vehicle-mounted recording system is recorded in time and the reason that withdraws from the non-volatile memory medium.
When (3) one of following fault (can be configured according to the operation demand) occurring, continue to maintain the driverless operation mode operation, ATP implements emergency braking immediately, man-machine interactive system continued to show failure message before fault was got rid of, emergency braking was alleviated after fault was got rid of, after emergency braking was alleviated, when ATO satisfied entry condition, ATP control ATO restarted:
1. the train mobile authorization withdraws;
2. train is received the state that platform screen door is opened or emergency stop push button is pressed in the platform zone;
When one of following fault (can be configured according to the operation demand) occurring, after keeping the driverless operation mode operation and coming to a complete stop to the position of turning back, do not turn back, the driverless operation pattern is withdrawed from prompting, and by described man-machine interactive system driver, transfer manual drive to after withdrawing from the driverless operation pattern.If withdraw from the reparation of driverless operation pattern prior fault, then continue to keep the driverless operation mode operation, can turn back and change end:
1. the default driving model of train tail end is not driverless operation;
2. train tail end ATP or ATO breakdown of equipment;
3. train tail end ATP and ATO communication failure;
When one of following fault (can be configured according to the operation demand) occurring, after keeping the driverless operation mode operation and coming to a complete stop to next operation platform or the position of turning back, driverless operation pattern and by described man-machine interactive system driver is withdrawed from prompting, transfers manual drive to after withdrawing from the driverless operation pattern.If withdraw from the reparation of driverless operation pattern prior fault, then continue to keep the driverless operation mode operation:
1. with the ATS communication failure.
When one of following fault (can be configured according to the operation demand) occurring, need immediately prompting to withdraw from the driverless operation pattern, withdraw from and transfer manual drive after the driverless operation pattern to:
2. the stop position deviation is excessive.
When one of following fault (can be configured according to the operation demand) occurring, need implement immediately emergency braking, need immediately prompting to withdraw from the driverless operation pattern after train comes to a complete stop, transfer manual drive to after withdrawing from the driverless operation pattern, withdraw from the driverless operation pattern before emergency braking can not alleviate:
1.ATO apply tractive force/braking force unusual or with the vehicle management system communication failure;
2. head and the tail devices communicating fault;
3. head end ATO breakdown of equipment;
4. communication failure between head end ATP and ATO;
Also there is following situation in the reality:
Train under the driverless operation pattern is turned back:
Equipment comes to a complete stop with driverless operation pattern control train driving to the position of turning back, if there is not the fault that need to withdraw from the driverless operation pattern, then turn back and change the end operation, change the front head end ATP of end the train operation state information exchange is crossed the head and the tail communication hand-over to tail end, tail end is after receiving handover information, and head and the tail are finished the handing-over of Train Control power, after obtaining mobile authorization, if ATO satisfies entry condition, then control the ATO startup and roll the position of turning back away from.
Communications status supervision under the driverless operation pattern:
Automatically under pattern was turned back in control, ATP need to continue to keep communications status with ATS, ground ATP, vehicle management system, applies the crucial operation informations such as state with reception traffic control, mobile authorization, traction braking.If the communication failures such as communication overtime, communication message be invalid occur, then withdraw from the driverless operation pattern.ATP continues to report the status information of driverless operation pattern to ATS, ground ATP, vehicle management system simultaneously.
Automatically dispatching a car under the driverless operation pattern:
Under the driverless operation pattern, ATO judges the non-security conditions of dispatching a car such as dwell time ends, and ATP judgement mobile authorization, platform screen door such as close at the condition of dispatching a car of safety, when the condition of dispatching a car of ATP, ATO all satisfies,, automatically dispatched a car by ATO control train to the ATO order of dispatching a car by ATP.
Accurate parking under the driverless operation pattern:
Under the driverless operation pattern, ATO guarantees at inlet parking, turns back, the accurate parking when returning section, thereby guarantee to stop operation, the operation of turning back, returns normally carrying out of section operation.If accurately do not stop because unforeseen circumstances causes train, ATO control train is again to attempt accurately parking than low velocity (for example 5km/h), if still can't stop standard, then report " accurately the stop position deviation is excessive " fault to ATP, and inform that by man-machine interactive system chaufeur manually stops.
Adjust the degree of automation of driverless operation pattern according to actual track running condition:
The set up the condition of driverless operation pattern and fault Rule of judgment can be configured according to actual track running condition, to satisfy different circuits for the different needs of equipment configuration and degree of automation.
For example, the set up the condition of configuration driverless operation pattern and fault Rule of judgment be not for checking two ends switch gate mode, then in actual operation, the switch gate mode can be made as " open Door by Hand and manually close the door " or " automatic door opening and manually close the door ", more up and down with passenger during satisfying the large conveying quantity circuit and stopping, the manual control lockup is to guarantee the passenger getting on/off security needs.
For example, the set up the condition of configuration driverless operation pattern and fault Rule of judgment be not for checking the ATO entry condition, ATP does not control the ATO startup simultaneously, then in reality operation still by manual activation ATO, guarantee departures safety to satisfy non-complete closed circuit, by the artificial needs such as dwell time adjust operation plan that prolong.
For example, the set up the condition of configuration driverless operation pattern and fault Rule of judgment be not for checking the state with ATS, then in actual operation, allow ATS to need not to keep communicating by letter with mobile unit, mobile unit is not when communicating by letter with ATS, drive train with the up-to-date operational plan that obtains before, in conjunction with artificial prolongation dwell time adjust operation plan, reduced the requirement to real-time communication, the needs of opening to satisfy part circuit reduction input cost or segmentation.
The present invention has following advantage:
1. the present invention has realized the full-automatic driving of train in the operation overall process, need not artificial participation, and the crew member only just need to carry out manual intervention to train driving in breakdown of equipment or urgent disaster scenarios it.Simultaneously the existing equipment of compatible train has the people manually to drive and people's automatic driving mode is arranged, and during the main track operation, can switch fast between driverless operation pattern and other driving models, has guaranteed can continue move with degraded mode under the failure condition;
2. but the part driverless operation is set up and the cutting of fault Rule of judgment, is used for regulating the gentle requirement to the line facility configuration of unpiloted Automated water, the needs of runing with the actual track that satisfies domestic high density large conveying quantity train operation.
3. comfortable, efficient, energy-conservation, can under the prerequisite that guarantees on schedule rate, at utmost utilize the energy-conservation characteristic of coasting according to the strategy that travels between the in real time automatic regulatory region of the circuit practical operation situation that ATS provides, improve simultaneously comfort of passenger.
Above embodiment only is used for explanation the present invention; and be not limitation of the present invention; the those of ordinary skill in relevant technologies field; in the situation that do not break away from the spirit and scope of the present invention; can also make a variety of changes and modification; therefore all technical schemes that are equal to also belong to category of the present invention, and scope of patent protection of the present invention should be defined by the claims.
